Photosynthesis
Organisms capture solar energy (energy from the sun) and store it as: ____________________
______________________________________________. The stored energy is then transferred
to ____________. All cells use this as an _____________________________________.
Photosynthesis is the absorption of ___________________ and production of ______________.
Cellular respiration is the transfer of energy from ______________ to _____________.
Where does photosynthesis occur?
Where does cellular respiration occur?
Green plants, cyanobacteria, & plantlike protists carry out _______________________________.
An autotroph is : ________________________________________________________________.
A heterotroph is: ________________________________________________________________.
What are three ‘categories’ of heterotrophs you know of?
Photosynthesis: The Process
The ________________ of the plant are specialized for photosynthesis. (Although it occurs in all
________________________ of a plant.)
The organelle where photosynthesis takes place is the ___________________________. These
organelles contain a double __________ membrane, and inner membranes forming compartments.
____________________ are stacked on top of one another. These stacks are called ____________.
The protein-rich fluid filling space between membranes is _________________. There are
molecules of ___________________ embedded in the thylakoid membrane. These molecules
absorb _____________________ and begin the process of photosynthesis.
On the following diagram label: chloroplast, granum, lamella, inner membrane, outer membrane, thylakoid, stroma
Write a word equation to represent the process of photosynthesis. (a word equation has
no numbers  ex. NaCl + H → HCl + Na results in the word equation: sodium chloride
and hydrogen produces hydrochloric acid and sodium)
Photosynthesis Word Equation:
Step 1: The Light Reactions
________________________ molecules trap light and transfer its _____________ to ATP.
Step 2: The Calvin Cycle
The chemical reactions that produce ____________________ from ____________________
are called the Calvin Cycle.
What is required for the Calvin Cycle to occur?
Which carbohydrate molecule is produced primarily by plants?
Accessory Pigments
The function of an accessory pigment is to _________________________________________.
Why do leaves appear green in the summer?
When temperatures cool down, the leaves stop producing green chlorophyll. After this, only
the pigments of orange ______________________, yellow ______________________ and red
_____________________ are left. This is the reason we see the characteristic colors of leaves
in the fall.
Wrap-Up Questions:
1. What is the source of carbon dioxide for land plants? Water plants?
2. What happens to the oxygen molecules formed during photosynthesis?
3. On another sheet of paper, create a labeled diagram/poster that you could use to teach
Grade 4 students the process of photosynthesis. It should be simple. Include the
following labels: sun, chloroplast, granum, thylakoids, light reactions, light energy,
source of CO2, Calvin Cycle, glucose, and oxygen. (Application – Out of 10)

You can use Fig. 4 on page 74 as a guide, but make a diagram/poster YOU understand!
You might also include the following labels: plant, leaf, energy, ATP, chlorophyll, starch
